SHIP-GALKING' MACHINE.

Specification of Letters Patent.

Patented Sept. it, 1918.

Application filed September 14, 1917. serial no. 191,376.

To all whom it may concern:

Be it known that I, MA'X Bruno TER= LESKY, a citizen of the UnitedStates, and a resident of Portland, in the county of Male nomah andState of Oregon, have invented new and useful Improvements inShip-Call:- ing Machines, of which the following is a specification.

My invention is an improvement in ship calking machines, and has for itsobject to provide a machine of the character specified capable of beingmoved along the seam between two boards and having means for comstraining the same to follow the seam, and having power operated calkingchisels for calking the same.

In the drawings:

Figure 1 is a front view of the improved machine, with parts in section;

Figs. 2, 3 and 4 are sections on the lines 2-2, 33 and 4- 1,respectively, of Fig. 1,

' each View looking in the direction of the ar- 'is adapted to run inthe seam rows adjacent to the line;

Fig. 5 is a section on the line 5-5 Fig. 2.

In the present embodiment of the invention, a supporting frame 1 isprovided having depending legs 2, and Within each pair of legs isjournaled a shaft 3 having wheels 4 for supporting the frame. Betweeneach pair of wheels 4 is arranged a wheel 5 which 6 between two boardsto guide the frame and constrain it to follow the seam. One of theshafts, namely, that at the front of the machine, is provided with asprocket wheel 6 which is connected by a chain 7 with a wheel 8 on atransmission shaft 9 journaled in the frame. This transmission shaft isdriven from a motor 10 mounted on the frame, through friction gearing.11 has a friction disk 12, by disks 13 and 14 on the 13 being featheredon a shaft, while the disk 14 is shaft.

Each of the disks 13 and 14 has a tire 16 of material having a highcoefficient of friction, as, for instance, rubber, and these tiresengage the face of the disk 12 on the motor shaft. The disks 13 and 14may be moved toward and from the center of the disk 12, by means oflevers 17 and 18, respectively, which engage annular grooves in the hubsof the disks. Each of the levers The motor shaft 7 is pivoted to toothedsector 19'0'1'1 the frame, and each lever has latch mechanismcooperating with the sector,

The 14 drives the shaft 9, while the disk 13,- which is feathered oh thesleeve 15, drives pulley 20 which is secured to the sleeve, this pulley20 is connected by a belt 21 with pulley oii-oii'e of a pair of feedrollers, the membersof the said pair beingdes i'gnated by the referencecharacters 23 24. Tlie'se fejed rollers are jest-salsa on the frame, andthe calking material, in dicated at 25, is fed by the rollers from asupporting reel 26 jouraaled on the frame. A feed plate 27 extends fromthe rollers to the scam, the lower edge of the feed plate being in suchposition that the calking material will pass from the plate into theseam, and the upper end of the plate is at the space between therollers. The plate is i11- clined as shown, and is tapering, graduallyincreasing in width toward its bottom.

The calking chisels 28 and 29 are connected with the piston rods 30 ofpistons 31 which are mounted in cylinders 32 supported on the frame.These cylinders are supplied with motive fluid through a pipe 33 whichleads from the motor 10, and valves 34 are provided in the pipe forcontrolling the flow of motive fluid to the chisels. Each chisel ispivoted to the piston rod, as indicated at 35, and a spring 36. isarranged adjacent to the chisel mally pressing the lower edge ofthechisel toward the feed plate, thus insurin the proper feeding of thematerial. It Wlll be noticed that the shaft of the roller 23 is extendedso that the pulley 22 is directly below the shaft 9.

In operation, when the motor is running fluid under pressure may besupplied to the cylinders, reciprocating the pistons and the chisels.The rollers 23 and 24 feed the calking material to the seam, and as thechisels 28 and 29 are reciprocated the material will be wedged into theseam. The speed of the feed may be controlled by the lever 17 while themachine may be moved as a wholelongitudinally of the seam through thedriving connection 7 this connection being controlled bythe lever 18. Itwill be understood that the chisel 29 may be omitted if desired. Theframe is extended above the pipe 33 to form a handle 37 for conveniencein manipulating the machine.

28, the said spring nor- I claim:

1. A calking machine comprising a Wheel supported frame, a motor on theframe, a driving connection between the motor and the Wheels for drivingthe Wheels, power 0perated chisels supported by the frame and driven bythe motor, means for connecting the chisels or the Wheels to the motor,means for constraining the chisels to follow the seam to be calked,means on the frame for supporting a strip of calking material, meanscontrolled by the motor for feeding the strip, means for varying therate of feed, and means for guiding the strip to the seam at thechisels, said means comprising an inclined plate leading from thefeeding means to the seam to be calked, the chisel being pivotallymounted and normally spring pressed to engage the plate.

2. A calking machine comprising a Wheel supported frame, a motor on theframe, a driving connection between the motor and five cents each, by

the Wheels for driving the Wheels, power 01;)- erated chisels supportedby the frame and driven by the motor, means for connecting the chiselsor the Wheels to the motor, means for constraining the chisels to followthe seam to be calked, feed rollers for the calkand an inclined feedingplate leading from the rollers to the seam at the chisels.

3. A calking machine comprising a frame, chisels supported by the frame,means for driving the chisels, said chisels being pivoted to the saiddriving means to swing trans versely of the seam to be calked, feedingmeans lateral to the chisels, a feed plate leading from the feedingmeans to the seam to be calked, and springs pressing the chisels intocontact With the plate.
